I have repeating table and a button which adds a row after click. Button has a code: ''thisXDocument.View.ExecuteAction(''xCollection::insert'',''Row_18'' ); And this code works but when I put this table into section it doesn't work. What shut I do??

I want to send a dataset to webservice but without using a ''New from data connection'' option. I want to do this using ''New Blank Form''. How to do this??
